My improved attachment may be readily attached to various forms of shovel blades, as well as the particular irrigation type illustrated in the drawing.

I claim the following:

In a load-retaining attachment for shovel blades, a hinge member adapted for attachment to the upper face of such blades at a point adjacent the forward edge and extending transversely of said blade, in combination with a load-retaining member provided with a hinge feature for engagement with said hinge member whereby said load-retaining member is adapted to have swinging movement and to be manipulated into a load-receiving position in which it extends rearwardly from said hinge member and is substantially parallel with and in juxtaposition with said blade, and to be actuated into its load-retaining position by the inertia of a gathered load as the shovel is being withdrawn from the material from which the load is being taken.
